What your AI can do with Cesure
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “create_score”: Create a score you write as a .cesure and open it as a draft, e.g. {"version":2,"score":{"title":"Song","tempo":96,"tracks":[{"name":"Guitar.”
“Use “import_score”: Open as a draft a score the person gives whole: a .cesure file's text, AlphaTex, or an "Open in Cesure" link. The score is taken as it is, n.”
“Use “read_score”: Read measures from..to of a track of the draft (all by default, 200 at most a call: past them, the answer's more says where to go on) as .ce.”
“Use “edit_measures”: Rewrite measures from..to (numbers, inclusive) of ONE track of the draft with .cesure measures, as read_score returns them; to = from - 1 in.”
How secure is the Cesure MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Cesure holds up.
Official endpoint
Operated by Cesure (cesure.app) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Cesure adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Pick Cesure
Choose Cesure in the gate directory. No sign-in needed.
Use it anywhere
Cesure's tools are live in every AI client you've connected — with rules and logging built in.

Who runs the Cesure MCP server?
The Cesure MCP server at a glance
https://api.cesure.app/mcpQuestions, answered
Is there an official Cesure MCP server?
Yes — Cesure operates its own remote MCP server at api.cesure.app. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect Cesure to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Cesure in the directory. No account or sign-in is needed. From then on, Cesure's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Cesure runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Cesure MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect Cesure in minutes. No credit card required.
